Machine control using real-time model

Summary by NHIP

Real-time machine control method

The method controls a machine subsystem using a qualified predictive model generated from prior geo-referenced data and real-time sensor data. The system calculates an error value to derive a model quality metric, which must meet a specific threshold to authorize operation control.

Abstract

A priori geo-referenced data is obtained for a worksite, along with field data that is collected by a sensor on a work machine that is performing an operation at the worksite. A predictive model is generated, while the machine is performing the operation, based on the geo-referenced data and the field data. A model quality metric is generated for the predictive model and is used to determine whether the predictive model is a qualified predicative model. If so, a control system controls a subsystem of the work machine, using the qualified predictive model, and a position of the work machine, to perform the operation.
